Acylsulfonamido- and sulfonamidopyridine-2-carboxylic acid esters and their pyridine N-oxides, processes for their preparation and their use as medicaments

ABSTRACT

The invention relates to acylsulfonamido- and sulfonamidopyridine-2-carboxylic acid esters and their pyridine N-oxides of the formula I    &lt;IMAGE&gt;  formula I  in which -A = R3 and B = X-NR5R6 or -B = R3 and A = X-NR5R6. -  The compounds are suitable as medicaments against fibrotic diseases.

The invention relates to acylsulfonamido- and sulfonamidopyridine-2-carboxylic acid esters and their pyridine N-oxides, and to their use as medicaments against fibrotic diseases.

Compounds which inhibit the enzymes proline hydroxylase and lysine hydroxylase cause very selective inhibition of collagen biosynthesis by influencing collagen-specific hydroxylation reactions. In the course thereof, protein-bound proline or lysine is hydroxylated by the enzymes proline hydroxylase and lysine hydroxylase respectively. If this reaction is suppressed by inhibitors, a hypohydroxylated collagen molecule which is not capable of functioning and can be released by cells into the extracellular space in only a small amount is formed. The hypohydroxylated collagen moreover cannot be incorporated into the collagen matrix and is very readily broken down proteolytically. As a consequence of these effects, the total amount of collagen deposited in the extracellular space is reduced.

Inhibitors of prolyl-hydroxylase are therefore suitable substances in the therapy of diseases where deposition of collagens contributes decisively to the syndrome. These include, inter alia, fibroses of the lungs, liver and skin (sclerodermia) and atherosclerosis.

It is known that the enzyme proline hydroxylase is inhibited effectively by pyridine-2,4-and -2,5-dicarboxylic acid (K. Majamaa et al., Eur. J. Biochem. 138 (1984) 239 to 245). However, these compounds are active as inhibitors in cell cultures only in very high concentrations (Tschank, G. et al., Biochem. J. 238 (1987) 625 to 633).

DE-A 34 32 094 describes pyridine-2,4- and -2,5-dicarboxylic acid diesters having 1 to 6 carbon atoms in the ester alkyl part as medicaments for inhibition of proline hydroxylase and lysine hydroxylase.

However, these lower alkyl diesters have the disadvantage that they are split into the acids too rapidly in the organism and do not arrive at their site of action in the cell in a sufficiently high concentration, and therefore are not particularly suitable for possible administration as medicaments.

DE-A 37 03 959, DE-A 37 03 962 and DE-A 37 03 963 describe, in general form, mixed esters/amides, higher alkyl diesters and diamides of pyridine-2,4- and -2,5-dicarboxylic acid which effectively inhibit collagen biosynthesis in the animal model.

There was thus the object of searching for compounds which have a more potent antifibrotic action than the compounds known to date.

The object is achieved by providing acylsulfonamido- and sulfonamidopyridine-2-carboxylic acid esters and their pyridine N-oxides of the formula I ##STR2## in which A=R³ and B=X--NR⁵ R⁶ or

B=R³ and A=X--NR⁵ R⁶ and

The invention furthermore relates to the use of compounds of the formula I and to their physiologically tolerated salts for the preparation of a medicament against fibrotic diseases.

Finally, the invention relates to the compounds of the formula I for use as medicaments.

The invention particularly relates to the compounds of the formula I for use as fibrosuppressants.

The invention furthermore relates to a process for the preparation of compounds of the formula I.

The invention furthermore relates to a process for the preparation of compounds of the formula I (specifically compounds of the formulae 3 and 8 or their N-oxides 3' and 8'):

a) Compounds in which X is a single bond are prepared as follows (Equation I): ##STR3## The equation applies both to 2,4-disubstituted pyridine derivatives of the formula I and to the 2,5-derivatives with all the substituents for R¹, R² and R³.

b) Compounds in which X is --CO-- are prepared as follows (Equation II): ##STR4## The equation applies both to 2,4-disubstituted pyridine derivatives of the formula I and to the 2,5-derivatives with all the substituents for R¹, R² and R³.

Re Equation I (process a)

i) 5-Aminopyridine-2-carboxylates of the formula 1 are reacted with compounds of the formula 2 in which Z is hydroxyl or a leaving group, which can be detached nucleophilically, and in particular is F, Cl, Br, I or tosylate, to give compounds of the formula 3. This reaction is carried out in a dipolar aprotic organic solvent or a solvent mixture. The following solvents are mentioned in particular: methylene chloride, carbon tetrachloride, butyl acetate, ethyl acetate, toluene, tetrahydrofuran, dimethoxyethane, 1,4-dioxane, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, dimethylsulfoxide, nitromethane and/or pyridine, if appropriate with addition of an acid-binding agent, such as ammonia, triethylamine or tributylamine, at a reaction temperature of 0° to 180° C., preferably 0° to 80° C. If Z is hydroxyl, the method is a condensation method which is known from peptide chemistry (cf. also Method B).

ii) The compounds of the formula 5 are esterified with an alcohol of the formula 4 by methods which are known and customary to the expert to give compounds of the formula 3. This method is used in particular if R⁴ in the compounds of the formula 3 which result from process i) is lower alkyl, in particular methyl. In this case, these compounds of the formula 3 are first hydrolyzed to the compounds of the formula 5 and then reacted with alcohols of the formula 4 in which R⁴ is not lower alkyl, in particular methyl.

The starting compounds for process ii), compounds of the formula 5, can be prepared by hydrolysis of the compounds of the formula 1.

The compounds of the formula 3 furthermore can be converted into the pyridine N-oxides 3' by methods which are known to the expert.

General instructions for this oxidation method are described in "E. Klingsberg, Pyridine and its Derivatives, Interscience Publishers, New York, 1961, Part 2, 93". Oxidation with hydrogen peroxide is described, for example, in "E. Ochiai, J. Org. Chem. 18, 534 (1953)". The process conditions can be found in detail in German Patent Applications P 38 26 471.4, 38 28 140.6, 39 24 093.2 and 40 01 002.3 and DE A 37 03 959, 37 03 962 and 37 03 963.

The preparation of the compounds of the formula 1, which are known from the literature, is described by N. Finch et al., J. Med. Che. (1978), Volume 21, page 1269 and Schneider and Harris, J. Org. Chem. (1984), Volume 49, page 3683.

Re Equation II (process b)

i) The pyridine-2-carboxylic acid 5-carboxylates of the formula 6 can be prepared from substituted pyridine-2,5-dicarboxylic acids (see CA: Volume 68, 1968, 68840 h). Suitable conditions are, for example, esterification with methanol in the presence of sulfuric acid, the reaction time being chosen such that complete esterification to the diester product takes place to only a minor degree, or the diester products can be separated off as by-products.

The compounds of the formula 8 are prepared from the compounds of the formula 6 and the amide derivatives of the formula 7, it being expedient to activate the two reactants with auxiliary reagents (Houben-Weyl: Methoden der Organischen Chemie [Methods of Organic Chemistry], Volume IX, Chapter 19, pages 636 to 637).

Reagents which can be used for carboxylic acid reactivation are the substances known to the expert, such as thionyl chloride, oxalyl chloride, pivaloyl chloride or chloroformic acid ester derivatives. It is not always necessary to isolate these activated derivatives of the compounds of the formula 7. It is usually expedient for them to be reacted with the sulfonamide derivatives of the formula 8 in situ after their preparation or as crude products.

The compounds of the formula 7 are expediently first reacted with an inorganic or organic base, such as, for example, sodium hydroxide, carbonate, alkoxide, hydride or amide, potassium hydroxide, carbonate, alkoxide, hydride or amide, ammonia, triethylamine, tributylamine or pyridine, at -20° to +150° C., preferably at 0° to -80° C., and this reaction mixture is reacted with a compound of the formula 6 or the activated form thereof. The reaction is carried out in an inert solvent, such as, for example, methylene chloride, methanol, ethanol, acetone, ethyl acetate, toluene, tetrahydrofuran, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, nitromethane, dimethyl sulfoxide or mixtures of these solvents.

ii) The compounds of the formula 9 are esterified with an alcohol of the formula 4 to give compounds of the formula 8 by methods which are known and customary to the expert (see Method a ii). In this case also, this method is used in particular if R⁴ in the compounds of the formula 8 which result from process i) is lower alkyl, in particular methyl. In this case, these compounds of the formula 8 are first hydrolyzed to the compounds of the formula 9 and then reacted with alcohols of the formula 4 in which R⁴ is not lower alkyl, in particular methyl.

iii) This method essentially corresponds to Method a i). Compounds of the formula 10 (preparation, for example, from 6) are reacted with compounds of the formula 2 in which Z is hydroxyl or a leaving group which can be detached nucleophilically, and in particular is F, Cl, Br, I or tosylate, to give compounds of the formula 8. This reaction is carried out in a dipolar aprotic organic solvent or a solvent mixture. The following solvents are mentioned in particular: methylene chloride, carbon tetrachloride, butyl acetate, ethyl acetate, toluene, tetrahydrofuran, dimethoxyethane, 1,4-dioxane, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, nitromethane and/or pyridine, if appropriate with addition of an acid-binding agent, such as ammonia, triethylamine or tributylamine, at a reaction temperature of 0° to 180° C., preferably 0° to 80° C. If Z is hydroxyl, the method is a condensation method which is known from peptide chemistry (cf. also Method B).

The compounds of the formula 8 furthermore can be converted into the pyridine N-oxides 8' by methods which are known to the expert. The information necessary for this is summarized under Method a ii).

Neutral compounds are employed for the preparation of compounds according to the formula I (3, 3', 8, 8') by Equations I and II. If appropriate, salt formation can be carried out after conclusion of the synthesis. Possible salt-forming agents are, preferably, N-alkylamines, (hydroxyalkyl)amines and (alkoxyalkyl)amines, such as, for example, 2-ethanolamine, 3-propanolamine, 2-methoxyethylamine, 2-ethoxyethylamine and α,α,α-tris-(hydroxymethyl)methylamine (=tris buffer or Tromethane) or basic amino acids, such as, for example, histidine, arginine and lysine.

The compounds of the formula I according to the invention have valuable pharmacological properties and exhibit, in particular, antifibrotic activity.

The antifibrotic action can be determined in the model of carbon tetrachloride-induced fibrosis of the liver. For this, rats are treated twice weekly with CCl₄ (1 ml/kg)--dissolved in olive oil. The test substance is administered daily, if appropriate even twice daily, perorally or intraperitoneally--dissolved in a suitable tolerated solvent. The extent of the liver fibrosis is determined histologically and the content of collagen in the liver is analyzed by hydroxyproline determination--as described by Kivirikko et al. (Anal. Biochem. 19, 249 et seq. (1967). The activity of the fibrogenesis can be determined by radioimmunological assay of collagen fragments and procollagen peptides in the serum. The compounds according to the invention are active in this model in concentrations of 1 to 100 mg/kg.

The activity of the fibrogenesis can be determined by radioimmunological assay of the N-terminal propeptide of the collagen type III or of the N- or C-terminal crosslinking domains of the collagen type IV (7s-collagen or type IV collagen NC₁) in the serum.

For this purpose, the hydroxyproline, procollagen III peptide, 7s-collagen and type IV collagen NC concentrations in the liver of

a) untreated rats (control)

b) rats to which carbon tetrachloride was administered (CCl₄ control)

c) rats to which first CCl₄ and then a compound according to the invention were administered

were measured (this test method is described by Rouiller, C., Experimental toxic injury of the liver; in The Liver, C. Rouiller, Volume 2, page 335 to 476, New York, Academic Press, 1964).

The compounds of the formula I can be used as medicaments in the form of pharmaceutical preparations which comprise them, if appropriate together with tolerated pharmaceutical excipients. The compounds can be used as medicines, for example in the form of pharmaceutical preparations which comprise these compounds as a mixture with a pharmaceutical, organic or inorganic excipient suitable for enteral, percutaneous or parenteral administration, such as, for example, water, gum arabic, gelatin, lactose, starch, magnesium stearate, talc, vegetable oils, polyalkylene glycols, petroleum jelly and the like.

They can be administered for this purpose orally in doses of 0.1 to 25 mg/kg/day, preferably 1 to 5 mg/kg/day, or parenterally in doses of 0.01 to 5 mg/kg/day, preferably 0.01 to 2.5 mg/kg/day, in particular 0.5 to 1.0 mg/kg/day. In serious cases, the dosage can also be increased. In many cases, however, lower doses are also sufficient. These data relate to an adult weighing 75 kg.

a) 5-[((4-((2-Phenylethyl)aminocarbonyl)phenylsulfonyl)amino)carbonyl]-pyridine-2-carboxylic acid

0.7 g (1.5 mmol) of the methyl ester described in Example 32b) were introduced into 100 ml of 1.5N methanolic NaOH at 20° C., while stirring. When a solution had formed, a crystalline product precipitated. The mixture was then stirred for a further 30 minutes. It was concentrated in vacuo, the residue was dissolved in a mixture of water and tetrahydrofuran, the solution was acidified to pH=1 with aqueous HCl and concentrated in vacuo and the colorless crystalline product was filtered off with suction. This gave 0.6 g, melting point 263° C. (with decomposition).

b) 5 drops of concentrated H₂ SO₄ were added to 0.5 g (1.1 mmol) of the above carboxylic acid in 30 ml of 3-pentanol and 20 ml of 1,4-dioxane, and the mixture was heated at 90° to 100° C. for 8 hours while stirring. The insoluble material was separated off, the solution was evaporated, and the residue was crystallized by means of water. This crude product was taken up in ethyl acetate, the solution was dried and evaporated, and the residue was chromatographed on silica gel using acetone/n-heptane (3:1). The fractions containing the title compound were evaporated, and the title compound was crystallized by means of diethyl ether. 0.045 g of the title compound was obtained; m.p. 234° to 235° C.

0.8 g (1.36 mmol) of the methyl ester from Example 68 was hydrolyzed with 30 ml 1N methanolic NaOH analogously to Example 112 a). After the mixture had been concentrated in vacuo, the residue was dissolved in tetrahydrofuran, the solution was acidified with 2N aqueous HCl and concentrated and the residue was treated with water and filtered off with suction. 0.75 g of product was isolated, melting point 149° C. (decomposition)

b) The title compound was obtained analogously to Example 2c). 4 drops of concentrated H₂ SO₄ were added to 1.04 g (2 mmol) of the above pyridine-2-carboxylic acid in 40 ml of 3-pentanol and the mixture was heated at 80° C. for 24 hours, while stirring. It was concentrated in vacuo and the resinous residue was crystallized with acetone to give 0.32 g of crude product; melting point 174° to 176° C. The mother liquor was concentrated, the residue was dissolved in methylene chloride and the solution was shaken with saturated aqueous NaHCO₃ solution. The organic phase was dried and the Na salt of the product was crystallized with acetone. This salt was suspended in tetrahydrofuran, the suspension was acidified with aqueous HCl, the clear solution formed was combined with the crystalline crude product, the mixture was concentrated and the residue was crystallized with ethyl acetate. This gave 0.54 g of colorless product; melting point 164° to 166° C.

a) 4-((Phenyl-n-butanoyl)amino)benzenesulfonamide 11.1 g (0.11 mol, 15.2 ml) of triethylamine were added to 16.5 g (0.1 mol) of 4-phenylbutyric acid in 300 ml of anhydrous tetrahydrofuran at 0° C. After 30 minutes, 12 g (0.11 mol, 10.5 ml) of ethyl chloroformate were added dropwise at 0° C. A solution of 18.1 g (0.105 mol) of 4-aminobenzenesulfonamide in 150 ml of anhydrous tetrahydrofuran was added dropwise to this thick suspension at -10° C. The mixture was stirred at 0° C. for 1 hour and at 25° C. for 1 hour and concentrated in vacuo, and the residue was treated with aqueous hydrochloric acid. The crystalline crude product was washed with water and recrystallized from 250 ml of methanol; yield 18 g; melting point 166° to 168° C.

b) 1.8 g (10 mmol) of 2-methylpyridine-2,5-dicarboxylate in 300 ml of acetonitrile were reacted with 3.2 g (10 mmol) of the above benzenesulfonamide, 2.1 g (10 mmol) of N,N'-dicyclohexylcarbodiimide and 1.2 g (10 mmol) of 4-N,N-dimethylaminopyridine analogously to Example 32b).

The undissolved substance was filtered off, the filtrate was concentrated, aqueous hydrochloric acid (pH 1) was added and the finely crystalline product was filtered off with suction. This product was dissolved in N,N-dimethylformamide, and water was added until clouding started. The crystalline crude product was washed with water and dried; 3.3 g; melting point 258° to 264° C. After chromatography with ethyl acetate/methanol (3:1) over silica gel, corresponding fractions were evaporated and the residue was recrystallized from methanol. 1.4 g of colorless crystalline product were isolated; melting point 258° C. (with decomposition).
